On my '91, which is a race car that I drive daily I get about 3 yrs./45K on ORielly lifetime pumps. ASP underdrives and 6000 RPM WOT shifts.
Ford, Napa, ORielly, are good. Avoid autozone. In any case inspect the pump carefully for quality and defects before you leave the store. If it looks questionable, leave it there.
